I. Field of the Invention
This invention relates generally to a LED light set and, more specifically, to an LED (Light Emitting Diode) light set that is smaller in physical size, easy to manufacture at lower cost, also has pantoscopic emission, waterproof and bendable characters.
II. Description of the Prior Art
Heretofore, it is known that the structure of current LED, as shown in
Based on the structure described above, if these known LED's are connected together as Christmas LED light set, manufacturers have to solder one pin of each of a plurality known LED's to conductive wire of positive power, and then solder other pin to negative power, the procedure is very tedious and cost is relative high that effects market competition.
The package, electrodes and pins are all external to the conductive wires, the whole size is relatively large, installation is not easy; light from the known LED's only emits from top of the package, that limits the luminance, the outlook is not attractive, all of these causes troublesome to users.
It is therefore a primary object of the invention to provide an LED light set that is smaller in physical size, easy to manufacture at lower cost, also has pantoscopic emission, waterproof and bendable characters.
In order to achieve the objective set forth, an LED light set in accordance with the present invention comprises at least one LED dice and two conductive wires covered by insulated layer, a holder is installed on the wires at every certain distance, one LED dice is installed on every holder; each of the LED dice connects to two conductive wires with very thin metal wires, every LED dice is wrapped with transparent package, the transparent package packs in the holder, LED dice, the thin metal wires and the conductive wires.
Based on above description, the present invention achieves smaller in physical size, easy to manufacture at lower cost, also has pantoscopic emission, waterproof and bendable characters.
The accomplishment of the above-mentioned object of the present invention will become apparent from the following description and its accompanying drawings which disclose illustrative an embodiment of the present invention, and are as follows:
A holder 20 is installed on the wire 2 at every certain distance, one LED dice 1 is installed on every holder 20; each of the LED dice 1 connects to two conductive wires 2, 3 directly or with very thin metal wires 30, then every LED dice 1 is wrapped with transparent package 5, the transparent package 5 packs in the holder 20, LED dice 1, the thin metal wires 30 and the conductive wires 2, 3.
The conductive wires 2, 3 mentioned above can be enamel-insulated wire; the holders 20 are formed by tooling compression or by grinding around the enamel-insulated wires.
Based on above description, the present invention applies package to wrap and connect LED dice, metal wires and conductive wires together to effectively reduce the physical size with waterproof character; to wrap and connect with package makes the structure of the present invention stronger and bendable at different angle and winding without damage; the present invention does not need to solder pins as prior art and can be manufactured in production line for lower manufacturing cost.
The LED dices in the present invention emit light out around the package for pantoscopic emission; the light is brighter and more beautiful.
While a preferred embodiment of the invention has been shown and described in detail, it will be readily understood and appreciated that numerous omissions, changes and additions may be made without departing from the spirit and scope of the invention.
